The Open Network (TON) is a blockchain platform originally conceived by the team behind the popular messaging app Telegram. First proposed in 2018, TON was designed to offer Telegram’s vast user base fast, secure, and scalable decentralized services—including payments, digital identity solutions, and more. With a goal of supporting millions of transactions per second, TON aims to foster a robust and accessible decentralized ecosystem.
Despite early regulatory challenges, TON has continued to evolve, drawing significant interest from the global blockchain community. It officially relaunched in September 2021, driven by open-source development and community support.
The History of TON
In 2018, Telegram introduced the Telegram Open Network through a whitepaper that outlined its vision and introduced its native token, Gram. The project quickly gained momentum, raising $1.7 billion in a private token sale—one of the largest in history at the time.
However, increased attention also attracted regulatory scrutiny. Prior to its planned public launch, the U.S. Securities and Exchange Commission (SEC) intervened, alleging that Gram tokens were unregistered securities. A legal battle ensued, culminating in a court ruling that forced Telegram to halt its blockchain plans and refund investors.
Despite this setback, the open-source nature of TON allowed developers and enthusiasts to continue its development independently. Community efforts led to the revival of the network, which has been growing steadily ever since.
How TON Works: Sharding and Dual-Blockchain Architecture
At the core of TON's functionality is its native cryptocurrency, Toncoin. This token facilitates various operations, including payments, staking, and governance.
TON employs a sharding mechanism to achieve scalability. Sharding allows the network to distribute workload across multiple smaller chains (shards), each capable of processing transactions concurrently. This significantly enhances throughput and reduces latency.
The network uses a Proof-of-Stake (PoS) consensus model, where validators are rewarded in Toncoin for verifying transactions. This is not only energy-efficient but also enables faster and cheaper transactions compared to Proof-of-Work systems.
TON consists of two primary components:
- Masterchain: The main blockchain that maintains general protocol information, including validator details and shardchain references.
- Workchains: Sub-blockchains that handle specific operations like smart contracts and transfers. Each workchain can be further divided into shardchains, allowing virtually unlimited horizontal scaling.
Key Features of TON
TON incorporates several advanced technical features that contribute to its efficiency and flexibility.
Actor Model
TON uses the Actor model for smart contract execution. This computational framework allows each contract to process messages independently, change its internal state, and send new messages. It enables massive concurrency, making the network highly scalable.
TON Virtual Machine (TVM)
The TON Virtual Machine is a deterministic, stack-based VM used to execute smart contracts. It is optimized for efficiency and ease of use, making it developer-friendly.
External Messaging
Smart contracts on TON can receive messages from external sources—including other blockchains and the internet. This allows off-chain systems and users without on-chain accounts to interact with TON contracts.
FunC Programming Language
FunC is a statically-typed programming language used for writing TON smart contracts. Developers use it alongside the standard library stdlib.fc to build decentralized applications.
Universality
Any account on TON can hold a balance and contain code and data. Even a basic wallet can function as a smart contract, offering developers exceptional flexibility.
Client Libraries
TON provides client libraries such as Tonlib, which supports Merkle proof verification. This allows clients to validate data received from the blockchain, enhancing security when interacting with external services.
TON Wallets
TON offers non-custodial wallets, giving users full control over their private keys and funds. These wallets allow users to send, receive, and store Toncoin securely. In addition, Telegram users can access a custodial wallet via the @wallet bot directly within the app, making it easy for beginners to manage digital assets.
Governance on TON
TON is a community-driven network. holders of Toncoin can participate in governance by voting on proposals related to protocol upgrades and changes. This democratic approach ensures that the ecosystem remains decentralized and aligned with users’ interests.
The Toncoin Token
Toncoin serves multiple purposes within the TON ecosystem, including:
- Paying for transaction fees
- Staking to secure the network
- Participating in governance votes
- Accessing services like TON DNS, TON Storage, and TON Proxy
The TON Ecosystem
TON is designed to be user-friendly and accessible, supporting a wide range of decentralized applications. Its ecosystem includes projects ranging from NFT marketplaces and gaming platforms to decentralized oracles and storage solutions.

TON vs. Solana vs. Ethereum
When comparing major blockchain platforms, users often evaluate them based on speed, performance, and scalability.
Block Time and Finality
- TON: Produces new blocks every 5 seconds. Cross-shard communication allows rapid transaction finality.
- Ethereum 2.0: Uses a slot-and-epoch system. Finality can take up to 12.8 minutes.
- Solana: Achieves sub-second block times but requires ~6.4 seconds for full finality.
Performance
- TON: Supports Turing-complete smart contracts across multiple workchains, enabling high throughput.
- Ethereum 2.0: Currently supports limited cross-shard transactions, restricting scalability for complex dApps.
- Solana: Optimized for high-speed simple transactions but may struggle with more complex operations.
Scalability
- TON: Uses dynamic sharding to support near-linear scaling, aiming for millions of transactions per second.
- Ethereum 2.0: Plans to scale using 64 shard chains, significantly improving over its current capacity.
- Solana: Does not use sharding, relying instead on other optimizations for speed.
Projects Built on TON
Several innovative projects are already leveraging TON’s technology:
- TON Auction: A decentralized platform supporting various auction types.
- OracleHub: A marketplace for data providers and smart contracts.
- TON Roulette: A blockchain-based gambling game.
- The Chat Game: An RPG that uses TON for in-game asset ownership.
Is TON a Good Investment?
TON’s scalable architecture and strong community support make it a promising Layer-1 blockchain. Its ability to handle high transaction volumes and support complex smart contracts could position it as a major player in the decentralized landscape.
However, as with any cryptocurrency, potential investors should conduct thorough research and consider market risks.
How to Buy Toncoin
Toncoin is available on several major centralized and decentralized exchanges. To purchase it, users typically need to:
- Create an account on a supported exchange.
- Complete identity verification procedures.
- Deposit funds (fiat or crypto).
- Buy Toncoin via spot or futures markets.
